I am planning to install a new pressure tank and water softener in my 25 year old home with copper pipes. We are on a private septic system and submersible pump well with fairly hard water. I have always been reluctant to install a water softener but removing the rust stains and scale from our plumbing fixtures has been a constant battle.

My first question is whether a water softener alone will solve our problems or should I be thinking about a whole house water filter instead or perhaps in addition to the water softener.

If both filter and softener are recommended, I'd like some advice as to where best to install the filter. (i.e. Before the pressure tank inlet or between the tank and the water softener?)

Thanks for any assistance you can provide.
